We’re happy to announce a new [release](https://github.com/snowplow/dbt-snowplow-unified/releases/tag/0.5.2) for Unified

### **Summary**

This patch release targets two issues existing users reported: adding a deduplication layer on the iso\_639\_3 seed that by default contains some duplicates to avoid possible duplicates in the sessions table, and using row\_number based deduplicating instead of qualify for Redshift that on certain versions can slow or halt the query processing.

### **Fixes**

- Deduplicate iso\_639\_3 seed (Close #99)
- Use row\_number to deduplicate in Redshift

### **Upgrading**

- Update the snowplow-unified version in your `packages.yml` file.
